Fraggles are mythical, mouselike creatures that live underground beneath a large vegetable garden. of the 100 fraggles in this population, 84 have green fur and 16 have gray fur. a dominant allele f confers green fur, and a recessive allele f confers gray fur. assuming hardy–weinberg equilibrium is operating, answer the following questions. (a) what is the frequency of the gray allele f? (b) what is the frequency of the green allele f? (c) how many fraggles are heterozygotes (ff)? (d) how many fraggles are homozygous recessive (ff)? (e) how many fraggles are homozygous dominant (ff)?

a)

b)

c)

d)

e)

Explanation:

It is given that  alleles for confers green fur (F) are dominant over allele for confers gray fur (f)

Given , out of fraggles, have gray furs.

Gray fur allele is recessive. Thus,  genotype for a recessive fraggle would be "ff", hence its frequency would be

a)

Thus, allele for recessive fraggle would be represented by "q" and it is equal to

b)

Allele for dominant allele would be represented by "p" and it is equal to

c) As per Hardy Weinberg's equation,

d) Fraggles are homozygous recessive (ff)

e) Fraggles are homozygous dominant (FF)

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
